For those who trace my spline pachting. This time general_x_spline type with a
lot of characteristics in one spline type available by setting freedom_degree
parameter:
- control points with freedom_degree=1.0 cause B-Spline shape (aproximiation)
- control points with freedom_degree=0.0 cause linear spline
- control points with freedom_degree=-1.0 cause Catmul-Rom Spline
(interpolation)
and all together can be mixed with very user-friendly way.

See thread with the same subject in povray.animations.
